source edit

GoogLeNet (Inception v1) feature-extracting backbone.

Builds a GoogLeNet with the paper-cited Szegedy 2015 topology: a Conv-MaxPool stem followed by nine _InceptionModule blocks at three resolutions (28×28 → 14×14 → 7×7) and a final lucid.nn.AdaptiveAvgPool2d to $1\times1$ . Approximately 6.8 M parameters in the backbone — roughly 12× fewer than AlexNet despite being substantially deeper.

Model Size

Parameters

pretrainedbool= False

Reserved for future pretrained-weight loading. Currently ignored — the returned model is randomly initialised.

**overridesobject= {}

Keyword overrides forwarded into GoogLeNetConfig (in_channels, etc.). Auxiliary-classifier fields are irrelevant for the backbone.

Returns

GoogLeNet

Backbone with the GoogLeNet configuration applied (or with overrides merged on top of it).

Notes

See Szegedy et al., "Going Deeper with Convolutions", CVPR 2015 — the ILSVRC-2014 classification winner with a top-5 ImageNet validation error of 6.67%. Single architecture; no paper-cited "tiny / large" variants (H11).

Examples

>>> import lucid
>>> from lucid.models.vision.googlenet import googlenet
>>> model = googlenet()
>>> x = lucid.randn(1, 3, 224, 224)
>>> out = model(x)
>>> out.logits.shape   # (B, 1024, 1, 1)
(1, 1024, 1, 1)
